Back in NetWorker 7.6 SP1, a new feature was introduced \u2013 Checkpoint backups. If you’ve not used or heard of then, you’ve probably not really even noticed how simple it is to turn on:<\/p>\n

\"Checkpoint<\/a><\/p>\n

The notion of checkpoint restarts is easy \u2013 if for some reason the connection to a backup fails during the process, rather than restarting it from the very start of the backup, NetWorker can restart it from either the last directory the save process had entered, or, the last file it had started.<\/p>\n

In theory, enabling checkpoint restarts is supposed to partially slow down the backup process \u2013 to keep track of checkpoints, NetWorker obviously has to do a little more work. In my tests, even with constructed filesystems having tens of millions of files, I’ve noticed very little performance difference between checkpoint restart backups and regular backups \u2013 and often in favour<\/em> of checkpoint restart backups. That being said, there’s obviously a reason why EMC says they can slow the backup down, so your mileage may vary.
\n<\/i><\/p>\n

But here’s the thing \u2013 if you’ve still got large fileservers running on Windows, Unix, etc., then checkpoint restarts are a no brainer. A backup of 4TB fileserver that can either restart from 0TB if the backup fails 3.9TB through, or restart at 3.8TB if the backup fails 3.9TB through: which would you prefer to deal with?<\/p>\n

Are you using checkpoint restart backups in NetWorker?<\/p>\n
